CORPORATION OF "WEST PNEUMATIC STACKER.

To all 107mm 'it may concern.'

Be it known that I, ALBERT M. Hamas, a citizen of the United States,residing at South Bend, in the county oit Saint Joseph and Sta-te ofIndiana, have invented certain new and useful Improvements in IneumaticStackers, of which the following is a speciication.

My invention relates to hoods tor pneumatic stackers ot' that charactershown and described in Letters Patent No. 845,876, issued March 5, 1907,to Abraham Luke, and consists in certain details oit construction andarrangements oil.E parts whereby I' am enabled to simplify theconstruction and, operation of such hood and materially improve theeliiciency thereof.

In the acconipanying drawings, which are made a part hereof, Figure l isa side elevation of my improved hood showing the bill thereof in loweredposition; Fig. 2 is a similar view showing the bill in raised position;Fig. 3, a bottom plan ot the same, and Fig. at a detail.

In said drawings the portions marked 10 represent the ordinary stackerchute to the outer end of which my improved hood may be rigidly orrevolubly secured. Said hood comprisesa lower tubular portion, l1,adapted to be fitted onto said chute 10 in any desired manner, theforward portion of the hood leading from said tubular portion assumingan approximately rectangular form and Composed of the side walls, 12,curved at their outer ends, as indicated by the dotted lines in Fig. 2,and the upper curved wall, 11i, said rectangular portion being open atits under side from the end of said tubular portion 11. In the patentreferred to it will be noted that the side walls of the hood are cutaway on an incline, and the space therebetween is inclosed by a hingedapron provided with cheeks which overlap said walls. This arrangement Ihave dispensed with, and cut the side walls of my improved hood on asubstantially straight line, leaving said walls of a height to conlinedischarging material and prevent its lateral escape. At the outer end ofthe tubular portion 11 I provide an adjustable delector, 15, hinged at16, which is semi-circular in form and lies within the walls 12, itslength being comparatively short in relation to the opening in saidhood, and at said hinge' point I also secure a Specification 0f LettersPatent.

rocker arm, 1.7, which entends around on each side ot' the hood, itsends being provided with eyes, 1S. Near the lower side of said walls 12I place reinforcing strips, 19, having their ends, 20, upt-urned to actas a stop for the rocher arm 17. By the arrangement just described I amenabled to materially reduce the main hood body in length and otherproportions. To the outer upper end ot said hood I hinge a bill, 25, asindicated at .27, and preferably reintorce the lower end of said bill bya strap- 'iron, 2S, to which I attach chains, 2t), or other flexibleretainers, and suitably connect them to the side walls or' the hood, lorlimiting the upward movement olf said bill .I further connect said hoodand bill by a coiled spring or springs, 30, as indicated in the drawing,which normally hold the bill in fully opened position, Fig. the upperside ot' the hood I provide a reinforcing strip, 33, which extends downslightly along each side wall and to which is secured a pair ot'sheaves, Bel, 35. while to the projecting ends, 236, of the reinforcingmember 2S, which extend down along each side wall of the bill 25, Isecure sheaves, To each end of the rocher-arm 17 I attach ropes orcords, 40, run the same about sheaves 34; and around sheaves 37 andthence over sheaves 35, and connect said cords at the rear of the hood,extending one thereof sulliciently to come within convenient reach ofthe stacker operator on the machine.

In operation, the bill is normally in the full opened position indicatedin Fig. 2, and so ar anged that the discharging material will have freeoutward passage to t-he fullest extent ot' the outlet of said hood. Asit becomes desirable to det-lect material downwardly, the rope t() ispulled, which, through the connection of its split ends with rockerarni17 and the sheaves described, simultaneously actuates the apron and thebill., so that as said bill is lowering said apron is incliningupwardly, which upward inclination delects the material upwardly tocause it to travel along the upper inner wall of said bill, the upwardmovement oi said deiiector being limited by contact of the ends ofrocker-arm 17 with the projections 20 on said hood. The stream ofmaterial is thus contracted as it passes through the bill and isdischarged in a compact mass. When said bill is pointed in its lowermostposition, as

On v

indicated in Fig. l, the material is discharged toward the separator, sothat the building of a stack may be commenced close thereto and thematerial gradually distributed rearwardly therefrom, as the size andheight of the stack increases, by lessening the pull on the cords 40,which permits the bill to automatically rise by the tension exertedthereon by spring 30.

I claim as my invention:

l. A hood for staclrers comprising a body portion having an opening inits under side, an upwardly adjustable semi-circular delector hinged atthe lower side of said body portion and extending partially across saidopening and within the side walls of said hood, a bill adjustablyconnected to the body portion and constituting a continuation thereof,and iiexible means communicating with said bill and deflector forsimultaneously adjusting the same.

2. A hood for staclers comprising a body portion having an openingtherein, an upwardly adjustable dei'lector hinged to the lower side ofsaid body portion and extending transversely across a portion thereof, arocker-arm on said deiector, a bill hinged to the outer portion of saidbody portion, and a means communicating with said rocker-arm and saidbill for adjusting said deflector and bill.

3. A hood for pneumatic stackers comprising a body portion having anopening therein, an upwardly swinging deliector hinged to the lower sideof said body portion and extending transversely across said opening,pulleys on said body portion, an adjustable spring-controlled billconnected to said body portion and having pulleys at its lower sides,and means communicating with said deflect-or and through said pulleyswith said bill for adjusting said deflector and bill.

4L. The combination, in a hood for pneumatie staolers, of an open-sidedbody portion, an upwardly adjustable delector hinged to the lower sideof said body portion and extending transversely across a portion of itsunder side, an adjustable bill at the outer end of said body portion, arockerarm attached to said delector, pulleys on said body portion,pulleys on said bill, and cords connected to said rocker-arm and passingaround said pulleys for adjusting said derlector and bill.

5. A hood for pneumatic stackers comprising a body portion having anopening therein, an upwardly adjustable deflector hinged to the lowerside ofsaid body portion and extending transversely across the lowerportion of said opening, and means on the side of said body portion forlimiting the upward movement of said deflector.

In testimony whereof I affix my signature in presence of two witnesses.
